I had went onto Minecraft I left it there for about 20 minutes on the start screen I hadn't pressed nothing at all so, so far I clicked the button to get the main menu I had went to my world I always play on and I spawned where I last played in a nether dungeon with nether bricks and I was running around to leave the nether and I used a wonder pearl to travel further and I made my way to to my nether portal and I was in the warped biome but I got a warped fungus and some red mushrooms and I went into my inventory to drop nether sprouts and I noticed a weird item it looked like a spawn egg I'll describe it (it has tan body and then there are like notches of brown fading into orange) it also fills up the item box and I use it to see if it's a food or mining tool which it isn't and I break blocks with it nothing is rewarded and it doesn't make anything go faster it's default hand speed I just got two of it I don't know how but I try to drop it and it stays there but it makes a drop sound I drop it from my inventory and it makes a drop sound but it drops and it's invisible with a circle shadow on it
